Interrupt settings on Proliant ML350G4 (BIOS)
When I received the box, interrupts could be selected to 3,5,11 (if I am not mistaken with the last one, 11).
After some playing around, suddenly all PCI interrupts are limited to either 3 or 5; be it USB, SCSI, NIC; you name it. The others are just unused. Also after booting, the OS shows those others being unused.
'top' shows an unusually high interrupt load at higher activity; and I am pondering on how to distribute the interrupts more evenly.
I have already erased NVRAM, but the limitation of irq3 or irq5 remains. How to get over this; what is my mistake ?
Why could I see three in the first place ?
Any help is highly appreciated,
Uwe

Re: Interrupt settings on Proliant ML350G4 (BIOS)
I have a very similar issue, different box. The interrupts on all 5 DL380 G4 servers I just received were all set to 5. I have the option of setting to 5, 7, or disabling.
I am hoping someone here may have a recommendation on how to set the IRQ's, and maybe an explanation as to why the options are so limited.
Thanks in advance!

Re: Interrupt settings on Proliant ML350G4 (BIOS)
If you disable the serial port and virtual serial port on the DL380 G4 you get IRQ 3 and IRQ 4 as well as 5 and 7. I'd still like to have access to 10, 11 and 15 as well though. It is as if the second interrupt controller isn't available... or isn't even there.
